BOX.

To all 'whom 'it may concern:

Be it known that I, SIEGMUND BACHMANN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventeda.new and useful Improvement in Boxes, of which the following is a specification. l

My invention relates to animprovement in the class of boxes, more commonly made of paper-board, involving in their manufacture the making of a blank of a desired form and bending such blank along folding lines to from which the produce the box, this' invention relating,

artieularly, to boxes in which the foldablle corner-extensions thereof are hinged to adjacent walls of the box. l

My -primary objects are to so construct boxes of the type above referred to as to render themlvery strong anddurable and proof against accidental displacement of the box-walls and in the accomplishment of these ends to use the minimum amount of stock.

Referring to the accompanying drawings, in which I have illustrated my invention in a few of the number of forms in which it may be embodied-Figure 1 is a perspective view of a foldable paper-board box illustrating a constructionthereof embodying one form of my invention. Fig. 2 is a similar view of the same showing the box in collapsed condition. Fig. 3 is a plan view of the blank box illustrated in the preceding figures is formed. Fig. 4 is an enlarged broken perspective view of one of the four similar corner-portions of the blank represented in Figp. Fig. 5 is a similar view showing a wall-portion of the blank and its adjacent corner-extension folded to erect position at which they extend at a rightangle to the base of the blank. Fig. 6 1s a view of the same showing adjacent walls erected with the corner-extension between l them folded into position against one of the walls, the views presented by Figs. 5 and 6 illustrating thev successive operations for folding the blank to produce one of the four similar corner-portions of the box and righting its walls. Fig. 7 is a broken plan View representing one or the four similarly constructed corners of the blank for another form of embodiment of my invention. .Figa

Fig. 10 is a similar view showing adjacent walls erected with the corner-extensions at their ends folded into position against one ofthe walls. Fig. 11 is a plan view of one of four similar cornerportions of a blank for forming another form of box embodying my invention. Fig. 12 is an enlarged broken perspective view of vone of the four similar corner-portions of the blank illustrated in Fig. 11. Fig. 13 is a similar View of the blank illustrated in Fig. l2 with one of its walls and its adjacent corner-extension folded to erect position at a Fig. 7 showing one of lright-angle to the'base of the blank. Fig. 14

is a similar view showing adjacent walls righted and the adjacent corner-extension folded againstl a -wall of the box. Fig. 15 is a broken plan View of one of the four similar corner-portions'of a collapsed box formed from the blank of Figs. l1 to 14 inclusive, showing the end-flap secured in place; and Fig. 15, a similar view of the box showing the end-flap in unfolded condition.

Each of the three constructions of the box selected for illustrating a different embodiment of my invention is of the collapsible patented sepa. 2s, i909.-

in Fig. 7. Fig. 9 is a type involving, generally stated, a base havmg four walls hingedly connected with the base, with extensions carried on the ends of opposed walls adapted to be folded fiat- Wise againstadjacent walls of thebox and held in positlon against accidental displacement by flaps carried by the walls against which the extensions are folded. Referring particularly to Figs. 1 to 6 inclusive, the box in its erect or non-collapsed condition is represented by Fig. `1. The blank (Fig. 3) from which this box is formed consists of an oblong rectangular sheet of box-board, or the like material, adapted vto be folded along the parallel dotted lines 18 and 19 to form the box-sides 20 and 21 hingedly connected with a base 22, and along thedotted lines 23 and 24. to form the box-ends or end-Walls 25 and 26, the dotted lines being, by preference, creases to facilitate folding the parts. Each line 18 lapsed-box *formed by The box thus formed. may folding tensions 27 of the side-walls of the blank, adapted to bel folded inwardlv along the outer extremities of the folding-lines 18, 19,

23 and 24 and along diagonal lines 28 (also preferably creases). Each corner-extension 27 is slit along the line 29 extending parallel with the sides of the extensions, and along a line 30 extending from thel inner end of the line 29 toward the edge of the extension to the middle of the diagonal folding line 28, the lines 28 and 30preferably being disposed at a right angle to each other. On each end of the blank is a -iiap 31 reaching preferably from the plane o the folding line 1-8 to that of the folding line 19, each iap being form the box from the blank the walls 20 and 21 may be turned upwardly upon their hinged connections with the base 22 to erect position as represented of the wall 2O in Fig. 5. The end-walls 25 and 26 may then be likewise erected, the extensions 27 in this operation folding inwardly upon the dotted lines 28, to cause theltriangu ar sections 33 the lines 28 and 30 and the exthe lines 18 and 19, to be folded against the inner sides of the end-walls and the tongues34 onthe ends of the extensions 27 to 11e fiatwise against the end-walls 25 and 26. The flaps 31, which may then be folded inwardly to overlapthe extensions, may be secured in such posltion in any suitable manner as is well understood in the art, as by fastening-devices such .as those indicated at 35, which preferably pass through the fiaps., tongues and end-walls of the box.

be collapsed b the side walls inwardly and the en walls outwardly, to cause the side-walls to lie against the base of the blank, the cornerextensions 27 in this operation s rin ing past the free ends ofthe aps an fol ing 'long the lines 28 and extensions 28a of. such lines to theposition illustrated in Fig. 2, from which condition the walls may be righted by pressing the side-walls outwardly and' drawing the end-walls upwardly and inwardly, the free ends of the flaps 31 being manually fiexed in this operation to permit the extensions to fold underneath them.. Instead of manipulating the blank as described to first erect and then colla se. the

tremities of box, the blank may be folded to t Ie colcondition illustrated in Fig. 2,`

without erecting the walls and thereu on applying the fastening-devices for the aps 31, a collapsed box thus formed being capable of ready erection when desired for use.

Referring particularly to Figs. 7 to 10 inclusive, the construct-ion of box therein illustrated differs from that presented by the preceding gures only in the formation of vline 37 extending para adapted to be folded at a dotted folding-Ime 32, as hereinafter described. To

essaie its' corner-portions. The corner-extensions 3G are formed by the intersecting of the lines 18 and 19 with the lines 23 and 24, each extension being preferabl severed along the lel with the lateralA edges of the blank, a line 38 preferably extending at a ri ht-angle tothe line 437 and reachinvr from t 1e line 37 to near the central longitudinal line of the extension, and a line 39 preferably parallel with the line 37 and extendin vfrom the point of its intersection with thefi folding l-ine 40, which latter terminates at the intersection of the adjacent folding lines defining the walls of the box. A box may be formed from the blankgthus provided by first folding the walls 20 `and 21 upon their hinged connections wlth the base 22v to-cause ne 38 to the outer end of a diagonal them to extend upward at right angles to t the base. The next operation is.

that of foldcause them to likewise extend at right-angles to the base and simultaneously therewith folding the extensions 36 inwardly 'along the diagonallines t0 to cause the quadrilateral sections 41 of the extensionsl defined-by the lines 38, 39 and 40 the folding-lines 18 and 19, to lie'against the surfaces of the walls 25 and 26, and the tongues 42 provided on the extensions beyond the sectionslil, to lie flatwise against the walls 25 and 26. The folded'downwardly and inwardly-to overlap the extensions and in such position be held in place, as indicated at 43 and described of the construction represented in Figs. 1 to' inclusive. A box thus formedmay be co1- lapsed by turning 'the and the end-walls outwardly,.the freeends of the flaps 31 permit-ting the extensions to 'be ing the end-walls 25 and 26 upwardly to' and the extremities of" fiaps 31 may then be side-.walls lnwa'r'dly withdrawn from engagement with such fiaps as described of-the construction ofthe-preceding figures. The extensionsl 36 in the operation. of collapsing the box unfold along' the lines 40 and the extensions 40El of the lines 10, the tongues 42 remaining in this Y in xed relation to the end-walls.

oeration I it is desire tofold the blank to Acollapsedboxfcondition without first righting the box it may be done as described of the construction of the preceding figures.'

As regards both of the constructions ldescribed in Figs. 1 to 10,inclusive,.they may be provided in the collapsed -forim with fasteningsdevices secured in-place intermediate the ends of the iaps 31 and holding the ton vues 34 and 42 in fixed relation Vto the end Awalls of the box, so that to erect the box, all

that is required is to throw the end-walls upwardly and inwardly, the side-walls outwardly and upwardly and flex the endpor V tions of the fiaps topermit the corner-extensions to extend under them.; or the boxes may be provided in the conditlon represented of the one in Fig. 2, excepting as tothe fastened i w1th, t

.for the dia'ps 31 being applied after the box is erected. 'From tl sase 'condition ofthe end-flapsll -Wh-ich may be unsecured to the walls carrying them, exceptin at Atheir hinged *connections theree application of the fastening means ie foregoing it will `be understood that when flaps, such as-those illus- 25 and 9.6

diagonal folding lines Walls by reason of the trated at 31 carried on the end-Walls, are used, it fis immaterial lhow they are 'fastened in place or when .such fastening takes place provided that `theflaps be lfastened in some manner when the'box 'is to-be used.

Inthe lconstruction illustrated in Fi s.'11 to 15* inclusive, the form of 'blank iiliers from that illustrated in fEi s.-7 lto 10 -inclusive only in the shaping o the corner-portions thereof. The corner-extensions 44 of this construction folding lines 45 posltionedsimilarly 'to the lines 28 and 40, and are severed along lines 46 parallel with-the edges of the extensions, the tongues 47 thus provided on the extensions 'being preferably of uniform width, as represented, instead of having their outer extremities enlarged as re resented of the this construction tongues 42. The lblank o may be erected t form a box by folding the side-walls 20 and yZ1 and the corner-,extensions 44 upwardly Fig. 13 and thereupon foldingthe end-walls upwardly and inwardly, the cor and' inwardly as represented in ner-extensions 44 in 'this operation folding inwardly along the foldinglines 45 and,the tongues 47 v,extending inwardly and 'lying againstl theI adjacent end-walls of the box. The flaps 3,1.may then -be folded down and secured in place as by fastening means, such as those represented at 48, passing through the flaps, -ltongues and end-walls as represented ofthe one in Fig. 14, the end-,portions of the flaps being thus free to be flexed. The box may l:be collapsed to the position of the one corner-portion represented in Fig. 15 by folding the side-walls 20 and 21 inwardly anddownwardly and thel end-walls 25 and 26 outwardly, it being designed that the ends of-theiiapsm be flexed in this operation to permit the swinv'ing portions-of the exten- 'sions 'to be withdrawn from under the ends of the lflaps to -lie dat against the base and end-Walls as represented, the tongues 4S) in this operation of colla sing the box remain'- in-gin yfixed position with relation to the endfolding off the cornerextensions 45l of the 45. To erect the box lthe condition represented in Fig. 15 the operator folds-the side-walls upwardly and outwardly and the end-Walls upwardly and inwardly, to cause them to extend at right-angles therewith 'flexes the ends of the flaps 3l upwardly to permit the movable" portions of the Icorner-extensions 44 to fold against the end-Walls 25 and 26 off the Ibox, whereupon extensions along Ithe are provided with diagonal f hingedly connected with to the base and simultaneously' the operator by releasing `his grasp onthe ends of the flaps permits them to spring into the position ofthe one `represented in Fig. 14. It ismani-fest that insteadof first erecting the box before reducing it to collalpsed condition, the blank may be folded to orm a collapsed box as represented in Fig. 15 rom Whichcondition it may be erected to form 'a box incondition .for use, as hereinafter described.

vWhile I prefer to provide the box in the collapsed condition represented in Fig. 15 in which the 4iiaps 31 are secured in place to the Walls carrying them, the box to b e erected for use Without applying fastening-devices after the box-Walls arefrighted, this is notnecessary as the boxes may :be lprovided in the collapsed condition represented in F ig. 15, in which the tongues 47 are secured in place against the end-walls 25 and 26 as by fastening-means indicated at 49, and the -tlaps 31 are in unsecured condition, it being intended that these flaps, when the box is erected, be secured, in any desirable manner, Ain position to overliethe corner-extensions.

It will be .noted that the feature common to all of the forms of the boxes illustrated and described which,.it will be understood, may be provided of Varying proportions best adapting them for isV that of p ro- ,viding on the foldable corner-extensions of a box, in which each corner-extension is the adjacent ends of the walls, a tongue which is hingedly connected with the extension carrying it and may be fastened to the adjacent Wallfor maintaining the corner-extensions .in fixed relation to the walls, the object of so constructing the extensions being that of providing means in a so-called uncut-corner box, for insuring the maintenance of the extensions in place when'the box is set up and' aiding in the operation of collapsing and erecting Ithe Walls. In the constructions illustrated in Figs. l to 10 inclusive, the tongues 34 and 42 are of a width approximately equal to .the height of the box-Walls and thus in addition to performing the function above stated, they serve to stitfen the walls against which they are secured.

While I have illustrated and described my invention as applied to boxes having flaps` such as those represented at- 31 on opposed Walls for holding the extensions inplace, I do 'not Wish to vbe understood as llmiting 4my invention to boxes employing Haps for this purpose, as any other suitable fasteningmeans, in addition to the tongues referred to, for holding the corner-extensions in place when the box-Walls are erected may be employed.

- Throughout .the foregoing description I have referred to lbox-ends and box-sides and the use to which it is desired they be placed,

thus permitting have specifically designated such parts in the drawings, but I do not wish to be understood thereby as limiting my invention in this particular, as such designations have been made merely for the purpose of aiding in the description of the invention. Furthermore, my invention is not only applicable to telescoping boxes in which the two parts are of substantially the same dimensions, but

to boxes, the sections of which are of different dimenslons, in which casewboth their body of the box and its cover, or either of these parts, may be constructed in accordance with my invention.

While the fastening tongues in each construction illustrated are so located as to cause their lupper edges, when secured to the wallsof the box,to extend close to the folding lines for the flaps 31,. I do not wish to be Iunderstood as limiting'my invention to such positioning of the flaps, as they may be disposed at any vother deslrable point on the extensions, this being desirable 1n boxes designed for hats or other articles requiring boxes of relatively great depth, in order that objectionable overlapping of the corner-extensions be avoided when the-box is erected, in which case the tongues would be' located on the extensions ,farther from the top edges thereof than is represented of the construe,

,tions illustrated.
